Specification of Letters Patent.

Patented July 1, 1922.

Application filed December 10, 1921. Serial No. 521.411.

To all whom it may concern:

Be it known that I, GEORGE A. Suns, citizen of the United States, and resident of Ilion, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

My invention relates to typewriting and like machines, and more particularly to means for mounting the paper table so that it may be readily detached from the machine when desired.

To the above and other ends which will hereinafter appear my invention consists in the features of construction, arrangements of parts and combinations of devices, set forth in the following description and particularly pointed out in the appended claims.

In the accompanying drawings, wherein like reference characters indicate corresponding parts in the various views,

Figure 1 is a vertical fore and aft sectional view of a typewriter carriage equipped with the devices ofmy invention, and with parts omitted.

Figure 2 is a fragmentary rear elevation of the same.

Figure 3 is a sectional view of the same taken on the line 33 of Fig. 1 and looking in the direction of the arrow at said line.

Figure 4: is a fragmentary view corresponding in part to Fig. 3 but representing one of the arms in the releasing position.

The present invention is in the nature of an improvement on a construction embodied in the No. 10 Remington machine and disclosed in the patent to Yaw No. 957302, dated May 10, 1910.

In the present instance the paper table is mounted for ready detachment from the machine, and is also pivotally supported for folding movement into and out of operative position. However, from certain aspects of my invention it is immaterial whether or not the paper table be mounted for folding or pivotal movement. 1

I have illustrated only so much of the carriage of a Remington typewriting machine as may be necessary to illustrate my invention in its embodiment therein, the invention being applicable to other typewriting and like machines.

The carriage, includes a platen frame which comprises end plates 1 on which a platen 2 is supported, said plates being connected by cross or tie-rods 3 and 1 fixedly connected to the end plates. Two bracket supporting blocks 5 are apertured to receive the tie-rod 4 on which the blocks are mounted and maintained spaced apart, the blocks be ing fixedly and firmly connected to the rod by suitable means. In the present instance the blocks are secured in place by pins 6 each of which passes through a hole in the blockat the apertured portion thereof, and through a corresponding hole in the rod. In addition to this, I prefer to solder each block to the rod to prevent any movement whatever of the block on the rod. The upper face 7 of each block preferably is flat and inclined downwardly and forwardly from the upper edge thereof. This face is tapped to receive the shanks of two screws 8 and 9 respectively. The shank of each screw 8 passes freely through a slightly enlarged opening 10 in a sheet metal supporting, or connecting, arm, or bracket plate 11, and is receivedin its tapped opening in the block, to pivotally connect the arm intermediate of its ends to the block. Each arm 11, in the normal or operative position thereof, extends fore and aft of the machine at an inclination corresponding substantially to the inclined face 7 of the associated block 5 on which it rests, and by which it is supported. The head of each screw 8 bears against the upper face of its arm 11, and when tightened binds the arm against the face of its supporting block and holds the arm against pivotal movement. The shank of each screw 9 is adapted to be received in the slot or recess 12 formed in one side edge of the companion arm 11. When the arms 11 are in the effective or operative position, shown in Fig. 3, and the screws 9 are tightened, the heads thereof bear down on the upper faces of the arms and clamp them to the supporting blocks and further hold the arms against pivotal movement. The lower end of each arm 11 is provided with an integral laterally projecting and outwardly extending pivot 13 adapted to be received in a pivot bearing, socket, seat or barrel 14, formed at the lower end of a sheet metal bracket plate 15 secured to the rear side of the paper table 16. The table in its operative position, shown in Fig. 1, is supported in an inclined position at the introductory side of the platen, said inclination corresponding substantially to the inclination of the arms 11. The upper end of each arm 11 is rounded at 17 to form an engaging member with which a spring catch 18, projecting from the rear side of the paper table, is adapted to coact to hold the latter against accidental movement around its pivots 18, while stop pins 19 carried by the paper table coact with the arms 11 to support the upper end portion of the paper table. i

It will be observed that the axis of each pivot screw 8 extends in a vertical fore and aft plane at right angles to the axis of the companion pivot 13 of the paper table. It follows therefore that a pivotal movement of, say, the left-hand arm 11 from the position shown in Fig. 3 to that indicated in Fig. 4, is effective to withdraw the companion pivot 13 from its seat 14 in the paper table and thus break .the inter locking connection between this arm and the paper table. As shown both arms 11 are pivoted and operable in the same man ner to withdraw the pivots, and thus readily direction.

effect a detachment of the paper table from the machine. It may suffice, however, in some instances, to pivot only one of the arms 11 in the manner described, the pivotal movement of oneof the arms enabling a detachment of the table to be effected.

It will be understood that in order to detach the paper table, the latter is first swung forward on its pivots 13, giving access to the screws 8 and 9. The latter are loosened to release the arms 11 and said arms are turned on'their pivots 8.

- It will be observed moreover that when the paper table is mounted 'in place, the outer edge 11? of each arm 11 coaots with the adjacent bearing 14: to prevent a longitudinal movement of the paper table in one The arms 'coacting with the bearings on opposite sides prevent a longitudinal displacement of the table in either direction; the arms 11 .being at this time firmly clamped against pivotal movement by V the'screws 8 and 9.

lVhat I claim as'new and desire to secure by Letters Patent, is

1. In a typewriting machine, the'combination of a carriage, a paper table, and means for detachably connecting the paper table to the carriage, said means comprising a hand released pivoted member which in one pivotal position connects the paper table to its support and in another pivotal position releases the paper table for'detachment. 7 v

- 2. In a typewriting machine, the combination of a carriage, a paper table, and means for detachably connecting the paper table to the carriage, said means comprising a pair of hand-released pivoted members located near opposite ends of the paper table and which connect the paper table to means for detachably connecting the paper table to the carriage, said means comprising a hand released plvoted member which in one pivotal position connects the paper table to its support and in another pivotal position releases the paper table for detachment, and means for secur ngsaid member against accidental displacement from its connecting position.
